Letters Patent No. 108,991, dated November 8, 1870.

IMPROVEMENT lN ASHSIFTERS.

The Schedule referred to' in these Letters Patent and making part of thesame.

To all 'whom it may concern.'

Be it known that we, WILLIAM S. EsTEY and ISAAC S. CLOUGH, of Brooklyn,in the county ot' Kingsand State of New York, have inventedza new anduseful` Improvement in Ash-Sitter; and wc d hereby declare that thefollowing is a. full, clear, and exact description thereof, which willenable others skilled in the art tov make and use the same, referencebeing had to the accompanying drawing forming part ofthis'speciicati'on.

Figure l is a Vertical longitudinal section of our improved ash-sifter.V,

Figure 2 is a front end view of the same.

Similar letters of reference indicate corresponding parts.

Our invention has for its object to furnish an iinproved sitter,designed especially for sifting ashes,` hut which shall be equallyapplicable for sifting Hour and other material, and which'shall be'simple in construction'eective in operation, and convenient in use; and

It consists in the l construction and combination of the various partsof the sifter, as hereinafter more fully described. i

A is the box of the sifter, which is made long and narrow, with inclinedsides and vertical ends, as shown in figs. l and 2.

By this construction the inclination of the sides of the box tends topack the sifted material and keeps it together, so that it may be morereadily .poured out without dust.

V13' isthe cover of the box, which is hinged at one of its side edgestothe upper edge of one of' the sides of the boxA, and is fastened atits other edge by-a hook or other convenient fastening.

The front end of the box A is made in three parts or pieces, al a2 a3.

rlhe upper piece al is securely attached to the lowe'r side of the endof the cover B, and the middle piece a2 is-secnrely attached to the endsof the sides ot' theA box A.

The upper edge of the piece a2 is hollowed or concaved, for conveniencein pouring out the coal or cinders, and the lower edge of the piece aIis convexed to fit into the concavity ot' the upper edge of the piecec2, and form a close joint.

The lower part a is secu-rely attached to the plate G, which is hingedat its-upper edge to the lower part of the piece a2. y

The side edges of the platea() project and may be bent `inward orflanged to overlap the ends of the sides of the box A, and its loweredge projects so as to overlap the end of the bottom ot' saidv box A, asshown in iigs. 1 and 2, to cover the joints ofthe piece a and preventthe escape of finev ashes or dust.

The piece a? and plate O thus form a door to enable Y Athe sifted ashesto be conveniently poured ont of the lower part of the sifter.

lheedoor a O is secured when closed byia hooker other convenientfastening.

. D are handles attached to the endsl of the box A, for convenience inhandling-and carrying it.

lhc sifting may be done by shaking the sifteror by rocking it upon itsbottom.

' The ashes may be poured ont first, or thecoal, according to thecircumstances under which the sifting may be done. E is the screen,which is made of wire-cloth, concaved or bent, as shown iu figs. and `2,and its side edges rest against the inclined sides of the box A.

The friction ofthe edges of the wire-cloth or 4screen- Ewill keep it inplace in the box A, or it may be secured by nails, buttons, or otherconvenient means.

This construction enables the wire-cloth or screelr to-bc readilyremoved and replaced' with a fineror' coax-ser screen, thus adapting thescreen for the use of drnggists or others who may desire to use thesitter for sifting different materials.

Having thus described our invention Y lVe claim as new and desire tosecure by Lettens" Patentj An improved sitter, formed' by the,combination of' the box A c1 c2 a, cover B, plate G, and screen E`, witheach other, said parts being constructed andoperating substantially asherein shown and described, and for the purpose set forth.
